I am not a citizenship lawyer nor do I play one on TV, but I am aware that American Citizenship by either parent goes to their children by default. When I was in the military, one of our contractors and his Greek Wife were killed in a car accident in 1997, the children were sent by the Greek American Embassy to the States as they we considered Americans Citizens to live with his Parents.
Citizenship is NOT the issue. The issue is a special kind of citizenship call NATURAL BORN citizenship. Cruz was born a citizen, he was NOT born naturally a citizen. Statutes were required to manifest his status. Freepers need to wake up.
